The question asks what Yves finds most interesting in Deauville. In the last paragraph the text states il ne put résister à la tentation d'aller à la rencontre de la mer ("he could not resist the temptation of going down to the sea"), and the text goes on to describe the sea in some detail. The correct answer is therefore (C) la mer ("the sea"). The first paragraph makes it clear that Yves is not very interested in the the town itself (la ville elle-même, (A)), the shopkeeper in the newstand (le marchand de journaux, (B)), or the passers-by (les passants, (D)).
